Overview
The W5100S is an embedded Internet controller chip designed by WIZnet, integrating a full hardwired TCP/IP stack with WIZnet technology. It provides internet connectivity to embedded systems via SPI (Serial Peripheral Interface) or Parallel System BUS. This chip is a one-chip solution for stable internet connectivity, supporting protocols such as TCP, UDP, ICMP, ARP, IGMP, and PPPoE. It is backward compatible with the W5100, allowing existing firmware to be used without modification.
